SLB-30-100NM 30.0 mm Dia. x -100.0 mm FL; Coated; Plano-Concave Lens 400-700nm

This is a Plano-Concave Spherical Lens, type SLB-30-100NM, sourced from OptoSigma. The lens has a diameter of 30.0 mm and a focal length of -100.0 mm, making it a negatively powered lens. The lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion.

The lens's geometry includes an edge thickness of 4.2 mm and a center thickness of 2.0 mm. The inner and outer radii are both 0 mm, indicating a flat surface on one side and a curved surface on the other. The curvature of the lens is defined by a radius of -51.9 mm on the curved side. The back focal length is -101.3 mm.

This lens is coated with an Opt M coating on both the front and back surfaces. This coating enhances the lens's performance in the spectral range of 400-700 nm, making it suitable for a wide range of applications, including but not limited to, imaging systems, beam shaping, and laser applications.
